职工管理系统

清华大佬耗费三个月吐血整理的几百G的资源,免费分享!....>>>

所用于codeblocks
1.单个职工的头文件
staff.h

#ifndef STAFF_H_INCLUDED
#define STAFF_H_INCLUDED

//结构体创建
struct staff
{
    char ID[10];
    char name[10];
    char sex[10];
    int pay;
    int reward;
    int factpay;
};
//自定义结构体

typedef struct staff staff;
//单个职工信息创建
staff Createstaff();
//单个职工信息输出
void Displaystaff(staff staff);
//修改职工信息
void updatestaff(staff *Staff);

#endif // STAFF_H_INCLUDED


单个职工的cpp文件
staff.cpp

#include <stdio.h>
#include <stdlib.h>
#include "staff.h"

staff Createstaff()
{
    staff staff;
    printf("-----------ID-----------\n");
    scanf("%s", staff.ID);
    printf("-----------name-----------\n");
    scanf("%s", staff.name);
    printf("-----------sex-----------\n");
    scanf("%s", staff.sex);
    printf("-----------pay-----------\n");
    scanf("%d", &staff.pay);
    printf("-----------reward-----------\n");
    scanf("%d", &staff.reward);
    staff.factpay = staff.pay + staff.reward;
    printf("\n");

    return staff;

}

void Displaystaff(staff staff)
{
    printf("%10s", staff.ID);
    printf("%10s", staff.name);
    printf("%10s", staff.sex);
    printf("%10d", staff.pay);
    printf("%10d", staff.reward);
    printf("%10d", staff.factpay);
    printf("\n");
}

void updatestaff(staff *Staff)
{
    printf("-----请显示要修改的数据--------\n");
    Displaystaff(*Staff);

    printf("-------请输入要修改的数据---------");
    printf("-----------pay-----------\n");
    scanf("%d", &Staff->pay);
    printf("-----------reward-----------\n");
    scanf("%d", &Staff->reward);
    Staff->factpay = Staff->pay + Staff->reward;
    printf("\n");

}

2.链表的创建
链表的头文件
linklist.h


#ifndef LINKLIST_H_INCLUDED
#define LINKLIST_H_INCLUDED
#include "staff.h"
//链表结点创建
struct Node
{
    struct staff Staff;
    struct Node *next;
};
//自定义结点

typedef struct Node node;
typedef struct Node *linklist;
//创建链表
node *Createlinklist();
//输出链表中的数据
void Displaylinklist(node *head);
//按职工号查找职工
node *searchnode(node *head, char ID[]);
//按姓名查找职工
void searchnodebyname(node *head, char name[]);
//删除职工
void delenode(linklist head, char ID[]);
//插入职工
void insertnode(linklist head, staff Staff);
//链表销毁
void distroylinklist(linklist head);

#endif // LINKLIST_H_INCLUDED

链表创建的源程序
linklist.cpp
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "staff.h"
#include "linklist.h"
node *Createlinklist()
{
    node *head, *p;

    head = (node *)malloc(sizeof(node));
    head->next = NULL;
    staff a[100] = {{"11111", "mmm", "f", 12000, 2000, 14000},
                {"22222", "aaa", "m", 13000, 3000, 16000},
                {"33333", "sss", "f", 15000, 3000, 18000},
                {"44444", "fff", "m", 17000, 8000, 25000},
                {"55555", "ggg", "f", 20000, 5000, 25000}};
    for(int i = 0; i<5; i++)
    {
        p = (node *)malloc(sizeof(node));
        p->Staff = a[i];

        p->next = head->next;
        head->next = p;
    }
    return head;
}


void Displaylinklist(node *head)
{
    linklist p;
    p = head->next;
    while(p!=NULL)
    {
        Displaystaff(p->Staff);
        p = p->next;
    }
}
node *searchnode(node *head, char ID[])
{
    linklist p;
    p = head;
    while(p!=NULL&&strcmp(p->next->Staff.ID, ID)!=0)
    {
        p = p->next;
    }
    return p->next;
}

void searchnodebyname(node *head, char name[])
{
    linklist p;
    p = head;
    while((p!=NULL)&&(strcmp((p->next)->Staff.name, name)!=0))
    {
        p = p->next;
    }
    printf("-----´ËÈËΪ---------\n");

    printf("%s", p->next->Staff.name);
    printf("\n");


}

void delenode(linklist head, char ID[])
{
    linklist p;
    p = head;
    while(p->next&&(strcmp(p->next->Staff.ID, ID)!=0))
    {
        p = p->next;
    }
    if(p->next)
    {

        p->next = p->next->next;
    }
    else
    {
        printf("=====NO FOUND========\n");
    }
}
void insertnode(linklist head, staff Staff)
{
    linklist p;
    p = (node *)malloc(sizeof(node));
    p->Staff = Staff;


    p->next = head->next;
    head->next = p;

}
void distroylinklist(linklist head)
{
    linklist p;
    p = head;
    while(p!=NULL)
    {
        p = p->next;
        free(p);
    }
}

3.文件存盘
file.h
#ifndef FILE_H_INCLUDED
#define FILE_H_INCLUDED
#include "linklist.h"
#include "staff.h"
//职工信息存盘
void saveinformation(linklist head );
//职工信息加载
void loadinformation(linklist head );


#endif // FILE_H_INCLUDED

file.cpp
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "file.h"
#include "linklist.h"
#include "staff.h"


void saveinformation(linklist h )
{
	FILE *fp;
	linklist p;

	if ( (fp = fopen("stu.txt","w") ) == NULL)
	{
		printf("Failure to open stu.txt!\n");
		exit(0);
	}


	for ( p = h->next; p; p=p->next  )
	{
	    fwrite( &(p->Staff), sizeof(node), 1, fp);
	}

	fclose(fp);
}





void loadinformation( linklist h )
{
	FILE *fp;
	staff nodeBuffer;


	if ((fp = fopen("stu.txt","r")) == NULL)
	{
		printf("\n\t数据文件丢失或为首次运行, 将加载测试数据\n");
		return ;
	}


	 while( fread(&nodeBuffer, sizeof(node), 1, fp)!=0 )
	{
		insertnode(h, nodeBuffer);
	}

}
4.主函数
mainmeun.cpp
#include <stdio.h>
#include <stdlib.h>
#include "linklist.h"
#include "staff.h"
#include "file.h"
void mainmeun(linklist head);

{
    linklist head=NULL;
    //int n;

    //printf("------请输入你要存的数据----------\n");
    //scanf("%d", &n);
    head = Createlinklist();
    system("cls");
    //Displaylinklist(head);

    mainmeun(head);
    printf("\n\n");
    //loadinformation(head);
    //saveinformation(head);
    return 0;
}
void mainmeun(linklist head)
{
    linklist p;

    char ID[10];
    //char name[10];

        case 8:
            flag = 0;
            break;

        }
    }while(flag == 1);
